This study aimed to evaluate whether adding straw to a loose-farrowing house promotes maternal functions and production. Forty-eight sows (Landrace × Large White) were housed in either a farrowing pen without straw (C, n=24) or with straw (S, n=24). Behaviors were observed using video recordings...

The present study was conducted to evaluate the effects of different rearing methods and stocking densities on carcass yield and proximate composition of meat in small-sized meat ducks. A total of 555 one-day-old birds were randomly allocated to six treatment groups (three replicates per treatment, ...

Stocking density is one of the major factors affecting production and welfare of fish in aquaculture. This study investigated the effect of different stocking densities on growth, feed efficiency, blood biochemistry, histometric response, muscular composition, and flesh quality of channel catfish ...

This study is aimed to explore the mechanism of overcrowding stress on the immunity of grass carp Ctenopharyngodon idella. Fish were reared for 120 days at 10 kg/m³ (low stocking density, LSD), 15 kg/m³ (medium stocking density, MSD) and 20 kg/m³ (high stocking density, HSD). The results showed...

An 8-week feeding trial was conducted to comprehensively investigate the effects of dietary phosphorus level and stocking density on tiger puffer. A 3 × 3 factorial design was used. The three dietary phosphorus levels were 0.68% (LP), 0.98% (MP), and 1.31% (HP) of dry matter, of which the available ...

Glucose and fructose play a central role in the metabolism and cellular homeostasis of organisms. Their absorption is co-mediated by two families of glucose transporters, Na⁺-coupled glucose co-transporters (SGLTs) and facilitative Na⁺-independent sugar carriers (GLUTs), in the intestine. However,...

Active transporters play a central role in the uptake and efflux of glutamate by cells and organelles. We aimed to assess the effects of crowding stress on the efficiency of active glutamate and glutamine transport in fish. We cloned intestinal-related transporters and investigated their...

Objective: The present paper aimed to study the effects of different breeding system. on emotional lotion (5-hydroxynyinomine 5-HT, beta-rnc6rphin 13-EP, Cortisol, etc.) and the mRNA expression of anti-prepant factor PI 1 gene. Method] TOW 60 60-day-old Sushong pigs (RW =28.4 z 0.30 kg) were...

In fish, aggression has significant individual differences, and different personalities exhibit distinct behavioral performances and physiological stress responses. Under intensive culture conditions, Sebastes schlegelii juveniles display severe aggression and cannibalism, causing damage to fish ...

The yellowtail clownfish (Amphiprion clarkii) is a hermaphrodite fish, whose sex differentiation and gonad development are closely related to its social status. The kisspeptin/KissR system is regarded as a key factor mediating social stress on reproductive regulation. In order to understand the...
